P14.5 251 Brake Chopper 1, 2, 3, 4 RW
When the frequency converter is decelerating the motor, the inertia of the motor and
the load is fed into an external brake resistor. This enables the frequency converter
to decelerate the load with a torque equal to that of acceleration (provided that the
correct brake resistor has been selected).
0 No brake chopper used
1 Brake chopper in use and tested when running. Can be tested also in READY
state
2 External brake chopper (no testing)
3 Used and tested in READY state and when running
4 Used when running (no testing)
P14.6 266 Flux Brake 1, 2, 3, 4 RW
Instead of DC braking, flux braking is a useful form of braking for motors <15 kW.
When braking is needed, the frequency is reduced and the flux in the motor is
increased, which in turn increases the motor’s capability to brake. Unlike DC braking,
the motor speed remains controlled during braking.
The flux braking can be set ON or OFF.
0 Flux braking OFF
1 Flux braking ON
Note: Flux braking converts the energy into heat in the motor, and should be used
intermittently to avoid motor damage.
P14.7 519 Flux Brake Current 1, 2, 3, 4 RW
Defines the flux braking current value. This value can be set P1.5 and P1.16.
P15.1 535 Fire Mode Function 2, 3, 4 RW
This parameter determines whether the fire mode function is determined by a
contact closure or contact opening on digital input.
0 Closing contact initiates fire mode function
1 Opening contact initiates fire mode function
P15.2 536 FMRefSel Function 2, 3, 4 RW
Setting this parameter to 1 enables the Fire Mode Frequency Reference 1 or Fire
Mode Frequency Reference 2 to be used as a reference in “Fire Mode” without
using a digital input.
0 Disabled
1 Enabled
P15.3 537 Fire Mode Min Frequency 2, 3, 4 RW
This parameter sets the minimum output frequency for fire mode.
P15.4 565 Fire Mode Freq Ref 1 2, 3, 4 RW
This parameter sets the drive operating frequency for fire mode reference 1.
P15.5 564 Fire Mode Freq Ref 2 2, 3, 4 RW
This parameter sets the drive operating frequency for fire mode reference 2.
P15.6 554 Smoke Purge Frequency 2, 3, 4 RW
Frequency setting for Smoke Purge.
P16.1 557 Motor Nom Current 2 2, 3, 4 RW
